Opening images or documents in a form by double clicking

[an1bone]

Hello,



I am working with images (JPEGs) and documents which vary depending on what record you are looking at. I have the file locations of the images/documents saved in the field of my table. Right now, I have the JPEG image appearing on the form when the specific record is specified. (I only have one image or document for each record.) I added an image to the form and set the image Control Source to the field with the image file location. My problem is that I want to be able to double click on the image to open it in a separate window (so that it can be zoomed in to read small text). Is there a way to do this??

Thank you much!

Paste this code into a module, and it will open ANY file in its native application.

usage:
OpenNativeApp "c:\folder\file.JPG" , will open the doc in your PC's default app for jpgs
and
OpenNativeApp "c:\folder\file.pdf" , will open it in acrobat

so you would use on the DOUBLE_CLICK event:

sub img_double_clic()
  OpenNativeApp txtBoxPath
end sub

'depending what is in the text box, it will open in its own app.

@ranman256 :

Can you go more in depth with where/how you use this code? I am still fairly new with VB. Can this code be pasted into the Events of an Image control in the form, or do I have to put it into the module? I want a preview of the image to show up on the form, and then open the file by double clicking on the image if that's possible. Thank you!

the bottom box code, goes into a module.

the form with the image, in the dbl-click event of that object put (or whatever txtBoxPath is called on your form.)
OpenNativeApp txtBoxPath
